"Quality, Productivity, and Competitive Position" and "Out of the Crisis" - W. E. Deming

"Workplace Management" - Taiichi Ohno

"Lean Six Sigma" - Jeffrey Ries

But aside from these "management philosophies", there's also standard industry/role practices that companies don't require their employees to implement, and when they do it's only enough to say they technically did it. Often the employees don't even know the standards exist. It's embarrassing.
